Black USB-to-DC cable with nine interchangeable barrel tips attached

USB to DC 5V Power Cord PK-549B with 9 Connectors Black

SKU CH-7PT3-FHP8N

Universal 5V USB power cable with nine interchangeable DC connectors for lamps, routers, fans and other low-voltage devices

  • Charges many 5 V devices from any USB port
  • Nine swappable tips cover 5.5×2.1 mm to 2.5 mm pins
  • Pure copper conductors give stable power delivery
  • Tough, eco-friendly jacket resists daily wear
  • Light, compact design fits easily in a travel bag

Universal 5V USB Power Cable

The PK-549B cable converts any standard USB port into a 5 V DC supply for small electronics. Nine interchangeable tips cover barrel and pin connectors from 2.5 mm up to 6.4 mm diameter. Pure copper conductors and a durable black jacket provide stable current delivery. It is aimed at owners of moon lamps, routers, mini fans, speakers and similar 5 V gear who want one compact lead for travel or desk use.

Suits owners of multiple 5 V peripherals

Users who power several devices with different barrel sizes benefit from the included adapter set. The cable draws power from power banks, wall chargers, car ports or laptop sockets. Devices that require voltages other than 5 V or need proprietary multi-pin connectors cannot use this cord. Buyers who need a fixed single-tip cable or higher current ratings should look elsewhere.

5 V DC output with nine swappable tips

The cable terminates in a 5.5 × 2.1 mm jack and ships with eight additional barrel plugs plus one 2.5 mm pin adapter. Listed tip diameters are 6.4 × 4.4 mm, 6.3 × 3.0 mm, 5.5 × 2.5 mm, 5.5 × 2.1 mm, 5.5 × 1.7 mm, 4.8 × 1.7 mm, 4.0 × 1.7 mm and 3.5 × 1.35 mm. Matching the device’s exact connector size and polarity is the deciding factor for compatibility.

Questions about this item

What USB power source do I need to run the PK-549B cable?

Any standard USB-A port such as a power bank, wall charger, car charger or computer port supplies the 5 V input the cable requires.

Will the included 5.5 × 2.1 mm tip fit the DC jack on my older router?

The set ships with a 5.5 × 2.1 mm connector plus eight other sizes ranging from 2.5 mm to 6.4 × 4.4 mm, covering most legacy 5 V router jacks.

How can I confirm the cable is delivering power after I plug it in?

The connected device should power on or show its charging indicator; the pure-copper conductor provides stable 5 V DC transmission when the correct tip is seated.
